| Abstract: | A 20 DOF (degree of freedom) hybrid stress element based upon Mindlin plate bending theory is developed using the optimizing design method for thin and moderately thick shell. It is of quadrilateral shape with only four corner nodes and can be used for both shallow and deep shells with excellent performance and the  shear locking problem no longer exists.The project supported by National Science Foundation of China. |
